CHAIR-BASE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed June s, 1908. Serial No. 437,225.

To all whom it may concern:

Be it known that I, ALBERT H. ORDWAY,

of South Framingham, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inChair-Bases, of which the following is a specification.

This invention relates to chair bases.

More particularly, it is designed for plat form rocking chairs, but itis applicable to other styles of chairs and articles of furniture.

In the accompanying drawings, Figure 1 represents a chair embodying oneform of the invention. Fig. 2 is a side elevation showing the structureof the base. Fig. 3 is a front elevation of the same. Fig. 4 is a planview of the same.

Referring to the drawings, and particularly to Fig. 2: The side framesof the base each consist of three curved pieces, preferably of bentwood, arranged somewhat in the form of a triangle. They comprise anunder arch 1, springing from the rear leg to the forward leg; an uppersemi-arch 2, springing from the rear leg forward and upward; and a frontpiece 3, rising from the front of the under arch 1 and supporting thefront of the semi-arch 2. Thus the entire side frame is composed ofthree pieces, two of which are joined to form one leg, two the otherleg, and at the same time two constitute longitudinal pieces and twoconstitute vertical pieces; and all three rest upon the floor. One tie,or stretcher or round 4 is inserted or socketed at the front in theangle between the under arch and the riser, and the other at the rear inthe angle between the under arch and the upper arch. At each of thesejoints a single pin or bolt 5, passing through the round, fastens allthree pieces firmly together; and a single pin 6 fastens the pieces 2and 3 together. Above the front round a single upper spreader 7 isprovided, having its ends bent downward into parallelism with the risers3 (see Fig. 3), to which it is fastened by pins 8. A screen of wickerwork may be arranged below it. There is only one round at the rear. Therocker bed consists of two beams 9, running fore and aft, which sustainthe springs on which the upper portion of the chair is mounted, thesebeams running between the front and rear rounds 4, and the springs beinginserted in the front and rear parts of each beam, as indicated at 10 inFigs. 2 and 4. Thus constructed, a light graceful and firm base isprovided, composed of very few parts, and with few and simplefastenings, yet abundantly strong. The bent wood construction makes thefull strength of the wood available. The suspension of the rounds in theangles above the under arch, as described, makes possible the strongsimple fastening, and holds them securely with a truss-like support andbalancing of stresses. The curved shape of the truss members adds to thestrength; and also the arrangement by which each foot is integral withtwo of the frame members which thus each contribute their fullstiffness.

The upper spreader 7 may be tenoned into the side frame, if preferred,and a similar joint may be made between the pieces 2 and 3. The rounds 4are also preferably set a little way into the pieces forming the angleswhere they are situated, as shown in Fig. 2.

In the chair illustrated in Fig. 1 the skeleton structure shown in theremaining figures is represented as covered with an ornamental weavingof wicker work; and in the rocking movement of the chair to and fro theseat and upper parts follow a line harmonious with the curve of the sideframe, thus contributing further to the symmetry and unity of the chair.

I claim:

A furniture base, composed of a platform and side supports therefor, inwhich-each side support comprises two arches, of bent wood, convexupward, one superposed on the other, the under arch being complete, theupper arch rising from one foot of the under arch and ending as anincomplete arch approximately over the other foot,

combined with a vertical support fast to signature, in presence of twoWitnesses, at said other foot of the under arch and joined Boston,Massachusetts, this 26th of Novemapproximately at right angles to saidend her, 1906.

of the upper; the said platform resting in ALBERT H. ORDWAY. the anglesbetween the said pieces on top I Witnesses: of the under arch. I M, E.MURPHY,

In testimony whereof I have afiixed my EVERETT E. KENT.
